CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Korean Patent Application No. 2006-123374, filed in the Korean Intellectual Property Office on Dec. 6, 2006, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

Aspects of the present invention relate to a hold function of an electronic device and, more particularly, to a method and an apparatus for automatically performing auxiliary functions of an electronic device while the device is in hold mode.

2. Description of the Related Art

Many conventional electronic devices have a hold function to prevent unwanted commands from being executed through the inadvertent pressing of function keys, which can happen when a user carries the electronic device in a pocket or bag.

When a user switches an electronic device to hold mode, it indicates that the user does not wish to input commands into the electronic device for the time being while the electronic device is in a pocket or bag. However, some conventional portable electronic devices do not take this fact into consideration, causing inconvenience to users.

For example, under normal conditions, if a user does not input commands using function keys for a certain time, the display of a portable electronic device automatically switches off if an auto off function has been enabled. When the electronic device is switched to hold, this action may be interpreted as the user not wanting to use the display for the time being, so it is desirable for the device to switch off the display immediately to conserve power. However, conventional electronic devices continue to maintain their current operating state, requiring users to manually deactivate the hold function and turn off the display to save power, which is inconvenient.

SUMMARY OF THE INVENTION

Aspects of the present invention provide an apparatus and method to perform auxiliary functions that a user wishes to have performed when the user switches an electronic device to a hold mode, thereby avoiding conventional problems associated with the hold function.

According to an aspect of the present invention, there is provided an apparatus to automatically perform auxiliary functions, the apparatus comprising a storage unit to store a table including conditions to perform the auxiliary functions in an electronic device; and a control unit to automatically perform the auxiliary functions when the conditions are met after a hold switch is switched on in the electronic device.

According to another aspect of the present invention, there is provided a method of automatically performing auxiliary functions, comprising switching on a hold switch of an electronic device; determining whether conditions for performing the auxiliary functions in the electronic device have been met; and automatically performing the auxiliary functions when the conditions for performing the auxiliary functions have been met.

 DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

FIG. 1 is a block diagram of an apparatus according to an embodiment of the present invention that automatically performs auxiliary functions in an electronic device while the device is in a hold mode. An electronic device 10 having the hold function may be one of various kinds of devices, including desktop computers, mobile phones, portable multimedia players (PMP), MPEG-1 audio layer 3 (MP3) players, digital media broadcasting (DMB) receivers, personal digital assistants, portable entertainment devices, and other portable devices that may require auxiliary functions to be performed automatically. The electronic device 10 includes a display unit 12, an input/output interface, a storage unit 13, a user input unit 14, and a control unit 15. The electronic device 10 may include various components such as a decoder, a buffer, speakers, etc. to perform innate functions of the device. However, these components are not shown in FIG. 1 for the sake of diagram conciseness.

The storage unit 13 stores a scenario table regarding the types of auxiliary functions to be performed by the electronic device and conditions under which the auxiliary functions are to be performed. An example scenario table is illustrated in FIG. 7. The table may have two categories (for example, the state of the electronic device and the auxiliary functions). The scenario table may be designed as part of pre-prepared firmware or software provided by the manufacturer of the electronic device or may be designed by a user.

The user input unit 14 relays a command to the control unit 15 allowing a user to control the electronic device and includes a hold switch. The hold switch may be a designated key or combination of keys, or other type of input (such as a mouse click).

FIG. 2 is a flowchart of a technique of automatically performing auxiliary functions in an electronic device according to an embodiment of the present invention. When the hold switch of the electronic device is switched on by a user in operation 21, it is determined in operation 22 whether an auxiliary function has been enabled. The auxiliary function may be pre-enabled by the user. If the auxiliary function has not been enabled, the automatic performing of the auxiliary function is terminated, and the electronic device is switched to a conventional hold mode in operation 26. In the hold state, the electronic device does not respond to any key input.

The current state of the electronic device is determined in operation 23. First, the state of the control unit 15 is determined. The state may be a function that the electronic device is performing, whether the mode of the processor of the electronic device is a dual mode or a single mode, and the number of programs currently loaded in the electronic device. The electronic device may have different states as well, according to other aspects of the invention.

It is determined in operation 24 whether conditions for performing the auxiliary function are satisfied. The control unit 15 refers to the scenario table (FIG. 7) stored in the storage unit to determine whether the current state of the electronic device determined in operation 23 matches any of the states of the electronic device included in the scenario table. If the conditions for performing the auxiliary function are not satisfied, the process of performing the auxiliary function is stopped and the electronic device is put in a conventional hold state in operation 26.

When it is determined in operation 23 that the conditions to perform the auxiliary function are met, the control unit 15 refers to the scenario table to automatically perform an auxiliary function corresponding to the current state of the electronic device. The auxiliary function is performed in operation 25. After the auxiliary function is performed, the electronic device is switched to a hold state in operation 26.

A technique of automatically performing auxiliary functions in an electronic device according to an embodiment of the present invention is described below with reference to FIGS. 3 through 6.

FIG. 3 illustrates a scenario in which a display, such as a liquid crystal display (LCD), is turned off when an electronic device is switched to a hold mode during audio only playback. First, it is determined in operation 32 whether the hold switch of the electronic device has been moved to an on position (in operation 31) and the auxiliary function has been activated. If the auxiliary function has been activated, then in operation 33 the current state of the electronic device 10 and the operation the electronic device 10 is performing are determined. If the electronic device 10 is currently playing back only audio, the control unit 15 searches the scenario table in FIG. 7 and determines in operation 34 whether “audio playback only” is included in the electronic device state category. If the “audio playback only” 71 is included in the electronic device state category, the control unit refers back to the scenario table, searches for an automatic performing of an “LCD off” 72 auxiliary function corresponding to the “audio playback only” 71, and turns the LCD off in the electronic device 10. In this scenario, when the electronic device 10 is playing back only audio, it is understood that the user does not wish to use the LCD.

FIG. 4 illustrates a scenario to end programs that are currently inactive when an electronic device that is performing a plurality of programs is set to the hold mode. First, when it is determined in operation 42 that the hold switch of the electronic device 10 has been switched on in operation 41 and an auxiliary function has been activated, the current state of the electronic device 10 and the operation the electronic device 10 is performing are determined in operation 43. If the electronic device 10 is loading a plurality of programs (for example, a file browser, a music player, and a video player), the control unit 15 determines in operation 44 whether “multiple program loading” is included in the scenario table. If “multiple program loading” 73 is included in the scenario table, the scenario table is referred to for performing an auxiliary function (e.g. “end inactive programs” 74) corresponding to the “multiple program loading” 73. For example, if a user switches on the hold function when the processor of the electronic device 10 is currently loading programs for a file browser and a video player, but only the video player is active and the file browser is inactive, this may be interpreted as the user wanting to only view a video file, so that the processor ends the inactive file browser to lower the load on the processor.

FIG. 5 illustrates a scenario where a hold switch is switched on while some of the multiple processing units of the electronic device 10 are active. Operations 51-53 are similar to operations 21-23 of FIG. 2. If only some of the multiple processing units of the electronic device 10 are active in operation 54, the inactive processing units are turned into power-off mode or sleep mode in operation 55. The electronic device 10 may include one conventional central processing unit (CPU) and one content decoder, or two conventional CPUs.

If the electronic device 10 includes a conventional CPU and a content decoder, and the CPU is running a document viewing program and the control decoder is playing back an MP3 file, then when the hold switch is turned on, the electronic device 10 presumes that the user will not be using the document viewing program for the time being. Therefore, the control unit 15 refers to the scenario table (shown in FIG. 7) and performs the auxiliary function corresponding to “some of multiple processing units are active” 75, i.e., “shut off power to other processing unit/sleep mode” 76. The controller 15 either shuts off power to the conventional CPU that was running the document viewing program or puts that CPU in sleep mode. Conversely, in other embodiments, the content decoder may have its power shut off or be put into sleep mode, and the MP3 file may be played back by the conventional CPU. Because conventional CPUs usually have low power consumption and slow processing speed, they are unsuitable for running a plurality of programs simultaneously. Thus, a conventional electronic device usually has a dual processor, including a conventional CPU and a content decoder. However, one CPU is sufficient when running only one program, so that the content decoder with its comparatively high power consumption may be replaced by the conventional CPU to play back MP3 files, in order to reduce power consumption.

FIG. 6 illustrates a scenario in which raw data to go through a database operation exists when a hold switch of the electronic device 10 is switched on. First, when the electronic device is switched to a hold mode in operation 61 and it is determined in operation 62 that an auxiliary function has been activated, the current state of the electronic device 10 and the operation the electronic device 10 is performing are determined in operation 63 and the scenario table (shown in FIG. 7) is consulted. When it is found that there is currently “raw data to go through database operation” 77, the control unit 15 performs “database operation” 78 of the raw data, in which the control unit 15 sorts and summarizes the raw data, and creates a database of the raw data. If the electronic device 10 is a mobile electronic device, there are many instances where the raw data included in the storage unit of the mobile electronic device, for example music files, go through a database operation before the raw data is stored. However, in order to perform a database operation on the raw data, much processing is required, which can burden the processor. For instance, in order to perform the database operation, the processor must extract database (DB) data or ID3 tag data (e.g. including artist, genre, song title, etc.) The extraction can impede other programs being run by the processor. Therefore, the database operation is difficult to perform while the raw data is input to the electronic device. It is desirable to perform the database operation a time when the processor has a low rate of use (for example, during a hold state).

The techniques of automatically performing the auxiliary functions according to aspects of the present invention may be recorded in computer-readable media including program instructions to implement various operations embodied by a computer. The media may also include, alone or in combination with the program instructions, data files, data structures, and the like. Examples of computer-readable media include magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD ROM disks and DVD; magneto-optical media such as optical disks; and hardware devices that are specially configured to store and perform program instructions, such as read-only memory (ROM), random access memory (RAM), flash memory, and the like; and a computer data signal embodied in a carrier wave comprising a compression source code segment and an encryption source code segment (such as data transmission through the Internet). Examples of program instructions include both machine code, such as produced by a compiler, and files containing higher level code that may be executed by the computer using an interpreter. The described hardware devices may be configured to act as one or more software modules in order to perform the operations of the above-described embodiments of the present invention.

Aspects of the present invention allow an electronic device to determine the needs of a user when the user switches on a hold mode in the electronic device, while at the same time determining the state of the electronic device, in order to perform needed auxiliary functions before switching to the hold mode. Thus, power is conserved and user convenience is enhanced.

Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
